2019-2020年高中英語 Unit2 Sporting events-grammar教案 牛津譯林版必修4 Step 1: General introduction Step 2: Practice 1. Now look at the blackboard, I’d like you to explain the meanings of the different modal verbs used in this sentence: I might/may/could/should/ought to/will/must watch the TV programme tonight. When might is used, it shows that the speaker is uncertain whether he or she will do something. When may is used, it shows that the speaker is s bit more certain than when might is used. Could is more certain than may, but less certain than should and ought to. Should and ought to are more certain. When we use will, we mean we are quite certain that we will do something. If we use must, we are almost certain to do something. 2. If you want to have a look at your friend’s book, what do you say? (Can I have a look at your book?) What does your friend say to you? (‘Of course, you can.’ Or ‘sorry/No, you can’t) So can is also used to ask for permission, especially in informal or spoken English. 3. Now read Part 1 on page 28 to find out how modal verbs are used to talk about ability, obligation, certainty and permission. Pay attention to the three arrows that illustrate the degrees of obligation, certainty and permission when modal verbs are used. 4. Read part 2 and use modal verbs to make requests, suggestions or offers, and give advice. e.g.: Will/Can you read the sentence once more? (To make a request.) Shall we watch a film tonight? (To make a suggestion) I will help you if you have any problems (To make an offer) The manager is not in now. You should e back at three o’clock (To give advice) 5. Now please read the instructions for the exercise on page 29. Then plete the article individually and I will check the answers later. (1) must (2) has to (3) must (4) must (5) should (6) ought to (7) could (8) may (9) could 6. Read Part 4 on page 28 and try your best to understand why the continuous form or the perfect form is used with a modal verb in the example sentences. First I’ll give you some examples: John isn’t here to attend the party. He must be reviewing his notes for the big exam tomorrow. (The speaker thinks that John is reviewing his notes now.) Tom knows nothing about the subject. He can’t have been at the lecture yesterday. (The speaker is sure that Tom did not go to the lecture yesterday.) The money is gone. Who could have taken it? (The speaker does not know who has taken the money.) Step 3: parison of some pairs of model verbs parison can, be able to shall, will need, dare mustn’t, needn’t 1. Read Part 1 on page 30 and find the differences between can and be able to. Be able to is more formal and less mon than can when referring to ability. Be able to can be used in different tenses or after other modal verbs, for example, will /shall be able to , would/should be able to , have/has /had been able to, must/may/might be able to. Be able to can be used after the infinitive marker to. The past form of be able to is was/were able to. Can is more mon and informal than be able to when referring to ability Can can be used to talk about a possible future action. The past form of can is could. Now please make some sentences with be able to and can, using different tenses, or after modal verbs or in a to-infinitive. 2. Read Part 2 and then plete the chart below. Shall Will In affirmatives expressing promises expressing determinations or decisions In questions making offers or suggestions for third person asking about willingness for the second and third person Make some sentences using shall or will. Let’s plete the dialogue ( Part B on page 31), and then read the dialogue in pairs to check your answers. B (1) Shall (2) shall (3) will (4) will/shall (5) will (6) will/shall (7) shall/will 3. Read Part 3 which explains the use of mustn’t and needn’t and then make sentences 4. Read Part 4 which explains when to use need or dare as modal verbs 5. Read the instructions for Part A on page 31, and then plete the passage. A (1) can (2) dare (3) can/could (4) may/might/could (5) mustn’t/shouldn’t/can’t (6) mustn’t/shouldn’t/can’t (7) can (8)needn’t Step 4: Consolidation I.
